The Atomic Clock Ensemble in Space is a fundamental physics mission of the European Space Agency to be launched in August 2021. It relies on a high-performance clock onboard the International Space Station (ISS), a network of high-performance clocks

We use data from the T-SAGE instrument on board the MICROSCOPE space mission to search for Lorentz violation in matter-gravity couplings as described by the Lorentz violating standard model extension (SME) coefficients $({\overline{a}}_{\mathrm{eff}}

International audience; We present the results of a local Lorentz invariance (LLI) test performed with the Cs-133 cold atom clock FO2, hosted at SYRTE. Such a test, relating the frequency shift between Cs-133 hyperfine Zeeman substates with the Loren

We introduce an improved model that links the frequency shift of the Cs133 hyperfine Zeeman transitions |F=3,mF⟩↔|F=4,mF⟩ to the Lorentz-violating Standard Model extension (SME) coefficients of the proton and neutron. The new model uses Lorentz
